mPRovEMENT :Nicolau-MARKER.

The Schedule referred to in these Letten Patent and part of the same.

`Rows; and I do hereby declare that the following is a true, full, and accurate description ofthe construction and operation of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon. y

Figure 1 represents a front view of the marker from the under side.

Figure 2 represents a front view of the centre-wheel and its connections.

Figure 3 represents a sectional side view of the centre-wheel, and the manner in which the uprights G, and metal collar and band I, are connected with the axle-tree.

Ais the oblong four-sided frame-work, made strong by the braces a a..

- B is the tongue.

C is the axle-tree, made with or without a joint in the cent-re.

The object of the joint in the axle-tree is to keep the marking-wheels upon the ground at all times, when marking uneven ground.

E E are standards, extending downward from either side ofthe` frame-work, at the end of vwhich are the stirrups D D, by which the axle is supported, and in which it revolves.

. .F F F are the wheels, or markers, one on each end of the axle, and the other in the centre.

These wheels, or markers are wedge-shaped from the centre to the edge, and the edges are covered with a rim of iron or other metal.

They are fitted to the axle with hubs of iron with smooth surface next tothe wheel, and the end-wheels are so constructed as to revolve with the axle, when the marker is doing its proper work, and to revolve around the axle whenever it is desired.

The centre-wheel is firmly fixed upon the axle, and only revolves when that does, and when it is desired to turn around forms a pivot, and holdsthe axle stationary, and the outer end-wheel, in describing a circle, revolves forward around the axle, and the inner end-wheel backward, or both can be made to revolve backward or forward at the same time, by keeping the axle firmly in its place.

The ends of the axle are perforated with holes, so

that the markers, or wheels can be adjusted so as to mark rows of any desired width.

Two uprights G G extend from the axle upward on each side of the centre-wheel, through openings in the cross-braces H H, which twov combined strengthen and support the axle and keep it in place, .when performing its work.

These uprights are attached to the axle by4 an iron band, within and around the metal collar I, which encircles the axle, and in which the axle revolves.

of metal, K, fastened by bolts and nuts to the foot of the uprights G G, which acts as a scraper.

L is a scraper-arm, consisting of a straight piece of wood of the same length as the axle, and arranged parallel with it, and supported underneath the rear of the frame-work by the staples l l, and in which it makes semi-revolutions.

On each end `of the scraper-arm is axeda scraper, M, projecting and extending over the wheels, or markers, and clawshaped.

The scraper-arm is perforated in the sam'e way as the axle, so as to allow the Scrapers to be shifted when the wheels are shifted.

N is a treadle, attached to the top of the scraper-l arm, near the centre, and extending out, so that the foot of the driver may be pressed upon it when necessary.

This scraper-arm, when not in use, carries the Scrapers up, away from the rims of the wheels.

The driver, by pressing his foot upon the treadle, makes it describe a half revolution, and brings the `Scrapers down close to the wheels.

secure by Letters Patent, is-

A, tongue B, revoiving jointed axle G, markers F, standards E, stirrups D, uprights G, braces H -H, scraper-arm L, scraper-s M, and treadle N, all arranged substantially in the manner herein described, and for the purposes set forth.

' 2. The arrangement and combination of the uprights G G, braces H H, and metal collar and band I, substantially in the manner herein described, and for the purposes set forth.
